How To Reboot Your Corpse

From Discovery News:

Thousands of bodies are already cryonically frozen, waiting for faster computers and medical advances that will undo their cause of death.

What is death? Over the centuries, the line dividing life and death has moved from the cessation first of breathing, then of the heartbeat, and finally of brain activity. But cryogenic methods first contemplated in science fiction may push the line even further. The idea is to freeze legally dead people in liquid nitrogen in the hope of regenerating them at some future date.

What It Takes to Keep a City Afloat -- Wall Street Journal

In One Day, the World's Largest Cruise Ship Prepares to Set Sail, with 700 Tons of Supplies, 80,000 Beers, and One Bagpiper

How do you keep more than 6,300 people fed, housed and having the time of their life while floating in the middle of the ocean?

The Oasis of the Seas—the world's largest cruise ship—aims to accomplish that feat nearly every week. Almost five times as large as the Titanic, it has a population during its seven-day Caribbean sailings that is larger than many American small towns—more than 8,600 when it is fully booked and including staff. The Royal Caribbean Cruises Ltd. ship, which first set sail last December, is almost as long as five Airbus A380 airplanes, or about four football fields. It has 24 restaurants and its own leafy "Central Park." During the weeklong sailings, about 700 tons of new supplies are needed, all loaded aboard each Saturday. Guests consume about 20 gallons of maraschino cherries and 80,000 bottles of beer.

Chile Earthquake Moved Entire City 10 Feet To The West

From Wired Science:

The magnitude 8.8 quake that struck near Maule, Chile, Feb. 27 moved the entire city of Concepcion 10 feet to the west.

Precise GPS measurements from before and after the earthquake, the fifth largest ever recorded by seismographs, show that the country’s capital, Santiago, moved 11 inches west. Even Buenos Aires, nearly 800 miles from the epicenter, shifted an inch. The image above uses red arrows to represent the relative direction and magnitude of the ground movement in the vicinity of the quake.

Pop star-turned-physicist Brian Cox speaks about his new TV series on the solar system.

It's big space, isn't it?

It's 93 million miles to the Sun: that's a long way. It takes light eight minutes to do that. There are 100bn galaxies in the observable universe. If you take a 5p coin and hold it 75 feet away, the space in the sky it would obscure would hold 10,000 galaxies. It's mindblowing. I don't think anyone has a grasp of that other than to say: it's big.

The Shocking Truth About Tasers

The new long-range Taser rifle, which can immobilise a suspect for 20 seconds from 100ft away, with an X26 pistol mounted beneath it.

A commuter in a diabetic coma, an 89-year-old man and children as young as 12 - just some of the targets of British police armed with skin-piercing 50,000-volt Taser guns. As the Home Office investigates bringing an even more powerful rifle version to Britain, Jason Benetto reports on the slow creep of arms onto our streets.

The smartly dressed sales executive travelling on the number 96 bus across Leeds didn't notice his body descending into a state of severe hypoglycaemia.

He didn't have time to ask his fellow passengers for help, or press the bell. Instead he slumped back in his seat in a diabetic coma, his head lolling from side to side.

US Lifts Web Sanctions On Cuba, Iran And Sudan

From The Guardian:

The US yesterday said it will allow export of instant messaging, web browsing and other communications technology to Cuba, Iran and Sudan, in an effort to facilitate the flow of information and promote freedom of speech.

The move by the US Treasury department comes after Iranian anti-regime protesters used Twitter, YouTube, Facebook and other sites to great effect in the aftermath of the disputed June elections. In the months since, anti-regime forces have used the technology to organise demonstrations, spread news and communicate with the outside world, including western journalists largely barred from covering the protest movement.

Science Daily (Mar. 7, 2010) — Scientists at the University of Rhode Island are gaining new insight into the mechanisms that generate huge, steep underwater waves that occur between layers of warm and cold water in coastal regions of the world's oceans.

David Farmer, a physical oceanographer and dean of the URI Graduate School of Oceanography, together with student Qiang Li, said that large amplitude, nonlinear internal waves can reach heights of 150 meters or more in the South China Sea, and the effects they have on surface wave fields ensure that they are readily observable from space.

Ice Once Covered The Equator

Two ideas exist on the progression of glaciation on Earth from 716.5 to 630 million years ago. Current evidence suggests the top version: a dynamic snowball Earth in which at least two long-lived glaciations happened during which communication between the ocean and the atmosphere was cut off. In this scenario, as CO2 built up, a hot-house effect ensued resulting in an ice-free planet at 670 and 630 million years ago. Credit: Zina Deretsky, National Science Foundation

Sea ice may have covered the Earth's surface all the way to the equator hundreds of millions of years ago, a new study finds, adding more evidence to the theory that a "snowball Earth" once existed.

Ultra-Efficient Gas Engine Passes Test

From Technology Review:

A novel fuel-injection system achieves 64 miles per gallon.

Transonic Combustion, a startup based in Camarillo, CA, has developed a fuel-injection system it says can improve the efficiency of gasoline engines by more than 50 percent. A test vehicle equipped with the technology gets 64 miles per gallon in highway driving, which is far better than more costly gas-electric hybrids, such as the Prius, which gets 48 miles per gallon on the highway.

The key is heating and pressurizing gasoline before injecting it into the combustion chamber, says Mike Rocke, Transonic's vice president of business development. This puts it into a supercritical state that allows for very fast and clean combustion, which in turn decreases the amount of fuel needed to propel a vehicle. The company also treats the gasoline with a catalyst that "activates" it, partially oxidizing it to enhance combustion.

From a nice girl, aged 37
Dear Carole, Why do girls – even nice girls – fall for bad boys, even when the girls in question are 37 and should know much better? My friends and I don't understand ourselves.

Carole replies:
The "dark triad" of human behaviour consists of narcissism (or self-obsession), psychopathy (including callous, impulsive, thrill-seeking, risk-taking behaviour) and Machiavellianism (exploitative, manipulative and deceitful behaviour). Bad boys exhibit dark triad traits and their behaviour, according to one theory, is genetic, meaning they are unlikely to change their ways.

Exotic Antimatter Detected at Relativistic Heavy Ion Collider: Heaviest Known Antinucleus Heralds New Frontier In Physics

The diagram above is known as the 3-D chart of the nuclides. The familiar Periodic Table arranges the elements according to their atomic number, Z, which determines the chemical properties of each element. Physicists are also concerned with the N axis, which gives the number of neutrons in the nucleus. The third axis represents strangeness, S, which is zero for all naturally occurring matter, but could be non-zero in the core of collapsed stars. Antinuclei lie at negative Z and N in the above chart, and the newly discovered antinucleus (magenta) now extends the 3-D chart into the new region of strange antimatter.
